14 Multiple presentation is less worrisome for me but should check each individual nail for invasion nail folds

26 Knuckle PADSKnuckle pads were medically first described by Garrod in 1893 and are also named Garrod's pads
27 There is no known established, generally successful therapy. Injection of corticosteroids (triamcinolone) can soften and sometimes even shrink the pads. Radiation therapy has also been reported to be successful in some cases but not consistently.Knuckle pads can be surgically removed in the case of pain associated with them. ..
28 Developmental defect rather than birthmark Aplasia Cutis CongenitaDevelopmental defect rather than birthmarkOccurs in about 1 in 5000 birthsUlcerated defects may heal with scar.
29 Although usually benign, the hair collar sign may be associated with other physical anomalies and malformation syndromes.No specific laboratory tests are required, although a hair collar sign signals the possibility of a CNS malformation and thus may warrant an MRI scan to rule out an underlying pathology
